Mastering the language of engineers
Geometrical Constructions, Curves & Scales
Dimensioning systems, BIS SP-46 standards, conic sections (ellipse, parabola, hyperbola), cycloidal curves, and constructable scales (Plain, Diagonal).
Orthographic Projections (Points, Lines, Planes)
First angle projection rules, projection of points, straight lines inclined to both HP & VP, and projections of regular planes surface inclinations.
Projections of Solids & Section of Solids
Projections of prisms, pyramids, cylinders, cones resting on HP/VP inclined to axes, and section planes cutting solids to reveal internal profiles.
Isometric Projections
Isometric scale construction, isometric views vs projections, blueprints of planes, prisms, pyramids, cylinders and composite solids.
Computer-Aided Drafting (CAD)
CAD UI setup, coordinate systems (relative, polar), basic 2D drawing command scripts (LINE, CIRCLE), and modify commands (TRIM, ARRAY).
🚨 1-DAY EXAM SURVIVAL PROTOCOL //
- 1. Master Unit II Lines: Guaranteed 14M question. Locus rotation method is mandatory.
- 2. Conic Construction: Practice General Method for Ellipse (Eccentricity). Very high recurring probability.
- 3. Sectioning Hatching: Always use light parallel lines at 45° for section surfaces to score neatness marks.
- 4. CAD Syntax: Memorize L, C, TR, F commands for the 5M theory bits.
- 5. Pencil Hygiene: Use 2H for all initial logic lines. HB only for final object profile.
